MOBILE, Ala. — After the morning weigh-in, NFL scouts, coaches and personnel men got their first look at the top senior prospects in two Monday afternoon practices.

A look at five players who have reason to feel good about their day and five more who saw their draft stock fall on Day 1 of Senior Bowl week:

GOOD IMPRESSIONS

Colin Kaepernick, QB, Nevada. Kaepernick (6-4 5/8, 225) looked much thicker and better-built than expected at the weigh-in. In practice, he showed excellent zip and accuracy to all points of the field. After having played in a spread offense in college, he looked comfortable in his first day running a pro-style offense. He used his eyes nicely to look off defensive backs, and he moved quickly through his progressions. He also kept the ball on an option play and turned the corner in a blink.

Leonard Hankerson, WR, Miami (Fla.). Hankerson (6-1 5/8, 205) caught everything thrown at him Monday and ran smooth routes. He used his body effectively to shield defenders from the ball and looked quick in and out of cuts. He showed great agility and balance catching multiple off-target passes.

James Brewer, OT, Indiana. Brewer (6-6 1/4, 323) flashed the quickness to get outside to stymie edge pass rushers, and he also showed strength and power as a run blocker. Although he lacks elite lateral agility, he stayed square to his target all afternoon, locking on his man.

Brooks Reed, DE, Arizona. Although Reed (6-2 1/2, 257) doesn't look impressive physically, he dominated one-on-one pass-rush drills, winning every matchup with a variety of moves. He started with speed to the edge, then spun back inside on the second rep and finished with a powerful bull rush.

Sam Acho, DE, Texas. Acho (6-1 3/4, 257) clearly has the size and athleticism to play defensive end in a 4-3 scheme or outside linebacker in a 3-4 defense. He has excellent arm length and showed the ability to win consistently with speed and quickness, but he lacks the power needed to bull rush or hold the point of attack vs. the run.

BAD IMPRESSIONS

Ricky Stanzi, QB, Iowa. Stanzi (6-4 1/8, 221) had a bad day and definitely looked the worst of the North quarterbacks. His passes showed no zip, and he did not show the arm strength to make deep throws. The biggest problem Monday was his terrible accuracy. Yes, he was working with new receivers, but his passes were all over the place. If he plays like this the rest of the week, he is certain to free-fall down draft boards.

Jake Locker, QB, Washington. For a player who came here with a ton to prove, Locker (6-2 1/4, 228) did not start off the week on a good note. Although he clearly showed the best mechanics of the North quarterbacks, his accuracy was all over the field. He seemed to be pressing and over-throwing much of the afternoon, causing many passes to float high. Locker definitely made a number of impressive NFL-caliber throws, but his inconsistency has to make NFL coaches nervous.

Lance Kendricks, TE, Wisconsin. Kendricks (6-3 1/8, 240) did not look natural catching the ball, trapping too many passing against his body instead of reaching out and plucking the ball out of the air. He did not look natural running routes; far too often he rounded them off rather than running them sharply.

Chris White, MLB, Mississippi State. White (6-2 7/8, 244) was out of place Monday; he looked stiff and lacked athleticism. He did not attack ballcarriers but tried basically just to catch them. He looked slow dropping into coverage and could not change direction quickly. He also took bad angles to ballcarriers and showed a lack of speed to recover.

DeMarcus Love, OT, Arkansas. Love (6-4 5/8, 318) continued his slide down draft boards, which began at the start of the 2010 season. He is a good enough athlete to play tackle in the NFL, but he really struggled throughout practice Monday. He was not aggressive with hands and again became a catch blocker, allowing defensive linemen to get into his chest and jolt/control him.
